Capistrano（> 3）中的這個錯誤阻止了我部署Rails應用程序。我的Capistrano配置在另一個環境中工作正常。Capistrano：NoMethodError：undefined方法`recv'for＃<IO:fd XX>

我正在使用代理連接到我的遠程服務器（在兩種環境中）。 SSH連接完美運行。
set :ssh_options, proxy: Net::SSH::Proxy::Command.new('ssh [email protected] -W %h:%p')
有沒有人遇到過這個問題？
解決方法
我的錯誤弱的理解是，SSH協商後，有時插座回到淨SSH是一個文件描述符這是意想不到的。 我已經加入：
gem 'sshkit', github: 'msimonin/sshkit', branch: 'gateway'
我的Gemfile使得ssh連接成立僅一次。
相關的配置是：
SSHKit.config.backend.configure do |ssh|
ssh.gateway = '[email protected]'
end
它正常工作，這種方式。我不能等待拉取請求被合併。
什麼是在另一個環境中的紅寶石和鋼軌版本，你是否使用類似的版本的Capistrano？ –
我使用的是完全相同的版本：Rails 4.1.0，ruby 2.1.1，Capistrano 3.2.1（不能與3.2.0一起工作） – Such
